First, let me say that I am a 56-year old non-techie guy. I've had every iPhone and at present do all I really need to do (web surfing, email, some videos, reading, etc.) with an iPhone 6 & iPad Mini retina. I've wanted to try my hand at a "real" Mac, but I don't want to...and don't especially see a need to spend the bucks for a new MBP until I learn the Mac OS and how to work it. I've messed with several MBP's at Best Buy and am generally confused by their total opposite from the PC's I use at work and am somewhat capable on. Here's my question: I have an opportunity to buy a like-new Apple MacBook A1181 from a local Craigslist seller. It's the white plastic model, but is perfect & is said to run that way...for $220. Is that a fair deal? Will it enable me to "get my feet wet" in the way Mac OS works reliably? Is it a good machine to start with? I appreciate your help, and advise!
